Answer:
n = 4.5
Step-by-step explanation:
I think it is 4.5 because n is 3 units ahead of 1.5 on the number line:
1.5+3=4.5
The expression of the unit rate was defined with all parameters rightly inputed the Molly's unit rate is 2.5 pages per minutes
<h3>Speed and Rate</h3>
Given Data
- Number of Pages read = 75 pages
The speed/ rate is defined as the number of pages read per minutes passed
Hence the expression for the unit rate is given as
Unit Rate = Number of pages/Time Taken
Substituting our given Parameters
Unit Rate = 75/30
Unit Rate = 2.5 pages per minutes

Answer:
the answer is A. 2370 sq. in
Step-by-step explanation:
area of the triangles first
A = 1/2 ad
a = (45 in) (20 in)
a = 1/2 (900 sq in)
a = 450 sq in
***remember to multiply 450 * 2 because you have 2 triangles***
Total area of both triangles is 900 sq. in.
Find the area of the 3 rectangles A = LW
1st rectangle and 2nd rectangle
a = cb
a = (30 in) (14 in)
a = 420 sq in. (make sure you add this again in the Total Surface area)
3rd rectangle
a = ab
a = (45 in) (14 in)
a = 630 sq. in
Total Surface area = 2 (1/2 ad) + 2(cb) + (ab)
= 2 (450 sq. in) + 2 (420 sq. in) + 630 sq. in
= 900 sq. in + 840 sq. in + 630 sq. in
= 2370 sq. in
Answer:
15 seconds
Step-by-step explanation:
Simply assume that total length to be covered be 'L'.
Now , 
of total length L is covered in time 
.
We know distance traveled =speed×time
Let Object's velocity be V
Using this
Thus, velocity in terms of total length is
Now,
To cover total length L time needed is
Time taken =15 seconds
